Just read this article The Motherboard Guide to Not Getting Hacked. It’s a bit of a long read but worthwhile. If you read this one from Brian Krebs as well, then you can show off at cocktail party’s.
I loved this part about privacy:
” Take a break from the wired world and meet people in person. If you stay out of earshot, you won’t be overheard, and your words will melt into the air, unsurveilled and unrecorded.
And besides, if you’re reading this guide, chances are that you really need a hug right now.”
